ARINC834A-1 ARINC 834A-1 Internet Protocol Based Aircraft Data Interface Function (ADIF)

This standard will define the  Secure Open Data and Avionics Services (SODAS), the transport layers, and the  suggested security mechanisms to enable communication between aircraft systems  and an Electronic Flight Bag (EFB). Herein is the definition of a set of  protocols and services for the exchange of aircraft avionics data across  aircraft networks. The purpose is to define a common set of services to be used  to access specific avionics data that will enhance EFB applications.

Supplement 1 introduces bi-directional communication between the EFB and FMS. It also enables mutual Transport Layer Security, incorporating client authentication.
